Double compacting technical structure for box molding machine

Abstract

The invention discloses a double compacting technical structure for a box molding machine, which comprises an upper pre-filling frame, an upper pre-filling frame oil cylinder, a sand box, a lower pre-filling frame, a lower pre-filling frame oil cylinder, a template, a template base, a template exchanging device, a compacting cylinder mechanism and a compacting element, wherein the sand box comprises an upper sand box and a lower sand box; the template comprises an upper template and a lower template; the template base comprises an upper template base and a lower template base; the upper pre-filling frame is supported by an oil cylinder, is mounted on the compacting element and is located above the sand box; and the lower pre-filling frame is supported by the oil cylinder, is mounted on the template base and is located under the sand box. A double compacting structure system with upper compacting technology and lower compacting technology is designed and arranged in a same molding machine, and the suitable molding technology can be selected according to the own characteristics and requirements of different product parts, so that the optimal compacting degree and sand molding quality are ensured.

Description

technical field [0001] The invention relates to a compacting process structure, in particular to a compacting process structure in box molding. Background technique [0002] Molding machines are casting equipment used to make sand molds. Its main functions are: filling sand, filling loose molding sand into the sand box; compacting sand, compacting the loose molding sand in the sand box through different methods such as vibration compaction, compaction, shock pressure, and injection pressure, so as to make the sand mold It has the necessary strength in the process of handling and pouring; the mold is lifted, and the pattern is taken out of the compacted sand mold by using different mechanisms. [0003] The original molding machine adopts a single compaction structure system. For different product parts, the appropriate molding process cannot be selected according to its own characteristics and requirements, and the ideal compactness and sand quality cannot be obtained.
